Δ3-Cyclopentenylmethyl-p-brom-benzolsulfonat, also known as 3-cyclopenten-1-ylmethyl 4-bromobenzenesulfonate, is a chemical compound with the molecular formula C12H13BrO3S. It is a derivative of cyclopentene, featuring a cyclopentenyl group attached to a benzyl moiety, which is further connected to a p-bromobenzenesulfonate group. Δ3-Cyclopentenylmethyl-p-brom-benzolsulfonat is often used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and other specialty chemicals. Its structure provides a unique set of reactivity patterns, making it a valuable building block for the creation of more complex molecules. The presence of the bromine atom on the benzene ring allows for further functionalization, while the cyclopentenyl group offers a rigid, five-membered ring system that can participate in various types of chemical reactions.
The CAS Registry Mumber 18593-39-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,5,9 and 3 respectively; the second part has 2 digits, 3 and 9 respectively. Calculate Digit Verification of CAS Registry Number 18593-39: (7*1)+(6*8)+(5*5)+(4*9)+(3*3)+(2*3)+(1*9)=140 140 % 10 = 0 So 18593-39-0 is a valid CAS Registry Number.
